Grade Copilot uses artificial intelligence to analyze student essays and instantly provides feedback on grammar, spelling, sentence structure, and more. It works with all types of essays, from research papers to personal narratives. Providing grading criteria will improve the accuracy of both the grading and feedback. Grade Copilot's feedback accuracy is comparable to human grading, and we are constantly working to improve its accuracy. Grading an essay with Grade Copilot only takes a few seconds, meaning teachers can grade more essays in less time. Grade Copilot does not write essays for students, it only provides feedback on essays that have already been written by students. Grade Copilot Pro subscription has no essay grading limits. You can grade 10 essays for free. If you like Grade Copilot, you can upgrade to a subscription for unlimited essay grading at $9 per month.
